重新编译 openssl-1.1.1、Python-3

编译安装openssl

openssl-1.1.1 https://www.openssl.org/source/openssl-1.1.1l.tar.gz

wget https://www.openssl.org/source/openssl-1.1.1l.tar.gz && 
tar -zxvf openssl-*.tar.gz && rm -rf openssl-*.tar.gz && 
cd openssl-* && 
./config --prefix=/usr/local/openssl && 
make -j4 && make install && 
ln -sf /usr/local/openssl/bin/openssl /usr/bin/openssl && 
ln -sf /usr/local/openssl/include/openssl /usr/include/openssl && 
ln -sf /usr/local/openssl/lib/libssl.so /usr/lib64/libssl.so && 
echo "/usr/local/openssl/lib" >> /etc/ld.so.conf && 
ldconfig -v

编译安装Python-3

weget https://www.python.org/ftp/python/3.7.9/Python-3.7.9.tar.xz && 
tar -xvf Python-*.tar.xz -C /opt/ && rm -rf Python-*.tar.xz && 
cd Python-* && 
./configure -prefix=/usr/local/python3.7 --with-openssl=/usr/local/openssl --enable-optimizations && 
make -j4 && make install && 
ln -sf /usr/local/python3.7/bin/python3.7 /usr/bin/python3.7 && 
ln -sf /usr/local/python3.7/bin/python3.7 /usr/bin/python3 && 
ln -sf /usr/local/python3.7/bin/python3.7 /usr/bin/python && 
ln -sf /usr/local/python3.7/bin/pip3 /usr/bin/pip3 && 
ln -sf /usr/local/python3.7/bin/pip3 /usr/bin/pip && 
/usr/local/python3.7/bin/python3 -m pip install --upgrade pip && 
/usr/local/python3.7/bin/python3 -m pip install --upgrade setuptools

pip 提示 ModuleNotFoundError: No module named '_ctypes' 

问题出在编译安装python前没有安装libffi-devel导致

yum install -y libffi-devel

重新编译安装python

make -j4 && make install

ModuleNotFoundError: No module named '_sqlite3'

编译前没有安装sqlite-devel 

yum install -y sqlite-devel

 重新编译安装python

make -j4 && make install
